You are migrating the branches of a customer to FortiGate devices. They require independent routing tables on the LAN side of the network.
After reviewing the design, you notice the firewall will have many BGP sessions as you have two data centers (DC) and two ISPs per DC while each branch is using at least 10 internal segments.
Based on this scenario, what would you suggest as the more efficient solution, considering that in the future the number of internal segments, DCs or internet links per DC will increase?
